Thanks for the advice. When I follow these steps, I cannot run the code it produces. It doesn't recognize "#include <iostream>" or cout. When I try running, it can't find the binaries. Do you know how to configure a project with libraries and a compiler? I'm not sure why that isn't set up automatically when I create the project...

Bump. Nothing about Eclipse is friendly to new users. The fact that 1200 people have viewed this page yet not a single person has given a worthwhile response is representative of the this problem.
I assume that OP, as well as with myself and the large number of others reading this, have already set-up a compiler. There's an Eclipse page on installing it. The problem is, after that, Eclipse still doesn't recognize basic includes like stdio.h even though the standard default main that's created with the project includes them. Default projects build automatically, since includes don't work, any call will not compile and eclipse throws "Launch Failed. Binary not found."

Don't tell us to read the manual. The manual would take literal days to read. If you want to export all of Eclipse's fundamental problems off this forum, at least specify where you want us to go.
